The Transpiration Ratio Measures the Relationship between Water Loss and Carbon Gain, which of the following statements about transpiration ratio is NOT true?

#Unit 6. System Physiology – Plant
  1. The concentration gradient driving water loss is about 50 times larger than that driving the influx of CO2 difference  is due to the low concentration of CO2 in air (about 0.03%) and the high concentration of water vapor within the leaf
  2. CO2 diffuses about 1.6 times more slowly through air than water does
  3. The CO2 molecule is larger than H2O and has a larger diffusion coefficient
  4. The concentration gradient driving uptake CO2 is about 50 times larger than that driving the water loss
